2. Description of the Related Art Normally, a recording paper read by an optical reader is selected from a plurality of prepared frames, and predetermined information is written by filling the inside of the frame. It is configured as follows.

[0003] Information written on such a recording sheet is read by an optical reader (OCR, OMR, etc.), converted into an electric signal, and input to a computer to be processed and processed. I have.

[0004]

By the way, when information written on a recording sheet is read by using an optical reader, complicated and various kinds of symbols such as alphabets and numerals are written on the recording sheet. In addition, there is a problem that the shape of the symbol is slightly shifted due to the habit of the writer, and it is difficult to identify the symbol by the optical reader.

In order to avoid this problem, conventionally, a point serving as a mark when writing a symbol on a recording sheet is arranged or a frame line is drawn, and an accurate symbol is revealed using the point or the frame line as a mark. However, it was not enough to wipe out the shape of the symbol.

For this reason, the invention described in Japanese Patent Application Laid-Open No. 3-59782 discloses an OCR for reading by an OCR device.
The area of the entry window of the R entry sheet is concave in cross section, and the writing implement is guided inside the entry window to prevent the characters from protruding.

In the invention described in the above-mentioned publication, a convex surface is formed by a bulging process so as to surround the area of the entry window, and the writing tool guides the user's writing instrument into the entry window by the convex surface, thereby preventing protrusion. At the same time, it prevents the characters from sticking out.

However, the concave and convex sections formed in the entry area such as the entry window of the entry sheet for OCR do not have minute steps, and when the scriber writes a symbol by applying force to the writing instrument, the concave and convex sections are formed. As a result, the function of the guide could not be performed, and characters and the like protruded from the entry window, and there was a possibility that an accurate symbol could not be described.

Further, the invention described in Japanese Utility Model Publication No. 45-15129 discloses a method for applying a coating of wax or vinyl to a partial area of a paper for a character reader in which the character is not desired to be written. To prevent overwriting.

However, in the invention described in the above-mentioned publication, since the punched vinyl or the like is attached to the partial area of the character reader paper where the character is not desired, the partial area where the character is not desired has a complicated shape. This makes it difficult to attach vinyl or the like to a narrow area, and there is a problem that the protrusion of the paint cannot be prevented.
